Anaesthetic puncture needle

Abstract

The invention discloses an anesthesia puncture needle, which comprises a support and a support plate, an outer sleeve is installed on the upper part of the support, an inner sleeve is installed in the inner cavity of the outer sleeve, a needle fixing rod is installed in the inner sleeve, and the needle fixing rod and the inner sleeve Threaded connection, a puncture needle installation hole is provided in the needle fixing rod, a puncture needle is installed in the puncture needle installation hole, a spring is installed on the outer periphery of the needle fixing rod, the two ends of the spring are in contact with the inner sleeve and the outer sleeve respectively, and the needle fixing rod is on the side wall A guide groove is set up, and a guide block is set at the bottom of the support, and the guide block is located in the guide groove. A vertical chute and an arc-shaped horizontal groove are set on the outer wall of the inner casing, and the arc-shaped horizontal groove and the vertical chute are connected. The positioning block is located in the arc-shaped horizontal groove. Its outer sleeve is equipped with an inner sleeve and a spring, and the inner sleeve is rotated relative to the outer sleeve so that the inner sleeve is free from the constraints of the outer sleeve. At this time, the spring can eject the inner sleeve and the puncture needle connected with the inner sleeve. The puncture needle is quickly withdrawn from the patient's body to achieve the purpose of rapid needle withdrawal and reduce the possibility of harm to the patient during the puncture process.

Description

technical field [0001] The invention relates to a medical device, specifically an anesthesia puncture needle. Background technique [0002] Anesthesia is a necessary procedure before the surgical operation. When performing anesthesia puncture with existing anesthesia puncture needles, there are following defects: 1. The anesthesia puncture angle is difficult to grasp, it is difficult to perform vertical puncture, and the puncture wound is relatively large, which easily makes the patient more painful; 2. With the existing puncture needles, in case of an emergency during the puncture process, it is difficult to quickly withdraw the needle, thereby easily causing damage to the patient's body. Contents of the invention [0003] The object of the present invention is to provide a kind of anesthesia puncture needle, it can solve the above-mentioned problem, and inner sleeve and spring are installed in its outer sleeve, and in an emergency, the inner sleeve can be rotated relativ...
